Uniform Collateral Data Portal (UCDP)
A web-based portal operated by Fannie Mae and Freddie Mac where appraisal reports are electronically submitted and checked for UAD compliance, data quality, and potential red flags before delivery to lenders.
All conventional mortgage appraisals must be submitted through UCDP before the loan can be delivered to the GSEs. The portal runs automated checks including UAD field compliance, data consistency, comparable selection logic, and flags for potential overvaluation or undervaluation. Submission Status Reports (SSRs) identify warnings and fatal errors that must be resolved. Lenders, AMCs, and appraisers all interact with UCDP as part of the loan origination workflow.
